If you work for yourself, you report business income and expenses on your own return and pay both halves of CPP. The return is due June 15, but any tax you owe is still due April 30. Register for GST/HST once sales pass $30,000.
Working for yourself changes who handles your tax. Nobody withholds it from your pay, so you report the income, work out what you owe, and pay on a schedule. The rules aren’t harder than an employee’s. The dates are just yours to keep.
What do you report?
You report your business income and subtract what it cost you to earn it. What’s left, your net business income, is taxed at your personal rates along with any other income you have. Keep receipts and invoices for every cost you claim, because the CRA can ask to see them for years afterwards.
The self-employed tax calculator turns net income into tax and CPP for your province. Our article on business expense deductions covers what usually qualifies.
How does CPP work when you’re self-employed?
An employee pays half of the CPP contribution and the employer pays the other half. When you work for yourself, you pay both. For 2026 the combined rate is 11.9% of net earnings between $3,500 and $74,600, which comes to as much as $8,460.90. The limits page shows the employee figures for comparison.
When do instalments apply?
Because no one withholds tax, the CRA may ask you to pay in four instalments, due March 15, June 15, September 15 and December 15. The tax instalments calculator checks if you must pay and splits the year into four payments.
Your return is due June 15, but the balance is due April 30. That gap catches plenty of first-year freelancers. The tax calendar puts both dates side by side.
When do you register for GST or HST?
Once your taxable sales pass $30,000 you have to register, charge the tax and file returns.
Below that it’s optional, and plenty of freelancers register early anyway, since you can’t claim back the tax you pay on a laptop or a software subscription until you’re in the system. The GST, HST, PST and QST guide has the whole picture.
Sole proprietor or corporation?
A sole proprietor and the business are one taxpayer. A corporation is a separate taxpayer with its own return and its own rates, and it brings extra filing and payroll work that you can’t skip. The corporate tax calculator shows the difference in tax, and the payroll remittance calculator covers what an employer sends the CRA.

Frequently asked questions
When is the tax return due if I am self-employed?
The filing deadline is June 15 for you and your spouse. Any tax you owe is still due April 30, so filing late in June does not delay the payment.
How much CPP do self-employed people pay?
You pay both the employee and the employer share. For 2026 that is 11.9% of net earnings between $3,500 and $74,600, up to $8,460.90.
Do I need to register for GST/HST?
Once your taxable sales pass $30,000 you must register. Below that it is optional, and some people register earlier to claim back tax on costs.
Should I pay tax instalments?
Nobody withholds tax from business income, so the CRA may ask for four payments a year. The instalments calculator checks whether the rule applies to you.
